Study Notes
Electrical Load
- An electrical load is any device or component in a circuit that consumes electrical power.
- Examples of electrical loads include appliances, lights, and motors.
Electrical Power Plant
- A power plant is an industrial facility that generates electricity.
Load Classifications by Service Type
- Domestic Load: Residential use
- Agriculture Load: Farming and agricultural applications
- Commercial Load: Business and retail establishments
- Industrial Load: Manufacturing and production facilities
Load Classifications by Nature
- Resistive Load: Consumes power by converting electrical energy into heat. Examples include heaters, toasters, and incandescent light bulbs
- Inductive Load: Uses magnetic fields to perform work. Examples include motors, transformers, and solenoids. Current lags behind voltage, resulting in a lagging power factor.
- Capacitive Load: Stores electrical energy in an electrostatic field. Examples include capacitor banks, cables, and capacitors used in motor starters.
Industrial Load
- Industrial loads primarily consist of induction motors, alongside lighting and other equipment.
- Industrial loads are often a combination of resistive, inductive, and capacitive loads.
